Hello.I'm new about efi flashing gpus for mac compatibility, and I need to know if it's possible to flash a Radeon HD3650 512Mb (it's a Gigabyte GV-RX365512H) with a EFI32 for a Mac Pro 1,1, and/or if there's a specific EFI32 module or if I can use a compatible one (like one for another ati radeon HD card).TIA.

P.s.: I also have an HD2350 64 Mb and an HD4650 1 Gb, and I would prefer to get the HD3650 as first choice, then the HD2350 if the first can't be done. And lastly the HD4650, but I still prefer not. Thanks again.

or, instead of reinventing the wheel for a $15 GPU, go WHOLE HOG and drop $25 for a 4870 and have an easy time.

Or blow your Christmas Bonus early and drop $45 for a 5770 or $55 for a 5870

Stick with the ones already done and written and you won't waste a lot of time

Look, I don't know how to get you and/or your answer, if you're trying to mock me or just you want to sound funny, or you're totally serious.I already have those 3 cards, the hd2350, the hd3650 and the hd4650, and I prefer to not waste money if it's possible to use one of those 3 cards.I don't want to reinvent the wheel or waste time trying for hacking's sake, I needed and asked for a simple answer to my question: if it's possible and maybe also already done, or not. It's as simple as it appears.
